UNITED STA CLARENCE LIPPER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO LIPPER MANU FAO'I'URING 00., IN 0., OF; PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF Re. 18,139 I PATENT OFFICE TEXTILE FABRIC I Original No. 1,888,689, dated January 8, 1929, Serial No. 310,873, flledOctober 6, 1928. Application for reissue filed February 19, 1929. Serial No. 341,154.

My invention relates to a new and useful improvement in textile fabric and it relates more particularly to a novel woven fabric having a resilient stiffening-mesh,'preferably on one sidet hereof, generally invisible from a surface thereof and Woven simultaneously with the body of the fabric and interlaced therewith at intervals sufficiently frequent to afford the body fabric the necessary support when in use. I

My invention relates more particularly to a novel textile fabric comprising a body formed of relatively flat, limp and bulky strands of artificial cellulose interlaced in any suitable manner and artificial cellulose stifi'enin strands having a different crosssectiona shape from that of the body strands and being relatively stifier and relativel less spacious than said body strands, inter aced with body strands-at suitable intervals and concealed by said body strands so as to be substantially invisible on a surface of the bod For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my -invention consists can be variously arranged and or nized and that my invention is not limite to the precise arrangement-and organization of the instrumentalities as herein shown and described. v

In the accompanying drawings illustrative of my invention and in which like reference characters indicate like parts:

Figure 1 represents a top plan view, :of a

fabric embodyin my invention, shown on a atly enlarge scale and in a somewhat 'a'grammatic manner. V

Figure 2 represents a plan view of the reverse orback side of the fabric similarly enlarged and also in a diagrammatic manner.

Fi re 3 re resents a section on line 33 of Flgure 2 ta en parallel to the war of the fabric andwith the warp threads of t e body omitted from the drawmg for eater clarity, and with the thickness of t ebody and weft threads much exaggerated for convenience and simplicity in illustration.

Figure 4 represents a section on line 14 -of Figure 2 taken parallel to the weft of the fabric and with the body weft threads omitt-ed for greater clarity, and with the thickness of the body-warp threads much exaggerated for convenience and simplicity in illustration. v

The novel fabric of my present invention may be woven onaloom with two sets of warp threads and two sets'of weft threads, or two shuttles.

The warp threads of the body as well as the weft threads of the body may be any suitablewarp and weft threads of the stiflening mesh or weave may be any suitable stiffening strands, such as horsehair, artificial fhorsehair, or the like.

In the particular embodiment of my invention shown in the drawings, the fabric is especially adapted for use in making ladies hats. Thus, for instance, in this particular embodiment I employ for the body warp and weft threads, suitable flatstrands of visca or other artificial cellulose product, such as artifi'cial straw.or the like. By artificial cellulose I comprehend the various regenerated cellulose products as well as cellulose derivatives. v

The body weft and warp strands designated by the numerals 1 and 2 respectively,

may each be composed of two or more independent v.flat threads of visca or other suit-.

able material and the general cross-section of the entire warp or. Weft strand is correspondingly flat.

In' Figures 3 and 4 of the drawings I have,

I formed of two flat threads a and b, although of weft and wa in actual practice more than two threads ma go to make up. a body warp and a body we strand.

Ohthe reverse side of the fabric, shown particularly in. Figure 2, two right angular'sets of stiffening strands are disposed, running weft-wise and warp-wise, and designated b the numerals 3 and '4 respectively. The stiffening threads 3 and 4 are preferably less frequent than the body weft and warp threads 1 and 2 res ctively and may be laid as fregently as esirable. In the particular emdiment of my invention illuS' rated inthe drawings there are one half as many stiffening strands as there are body weft and warp strands. Thus, the stiffening strands 3 and 4 are interwoven with each other in a plain weave .to form a relatively open mesh or.

gauze on' the reverse 'side surface of the body of the fabric.

The'weave of the body of the fabric 'formed strands 1 and 2and the weave of the sti ening mesh formed of the strands 3- and 4 are'preferably independent of each other except for an occasional interlacing of the warp reinforcing threads 4,wi-th the a threadsof certain of the weft body strands 1. Thus, in the particular embodiment of my invention shown in the drawings, the ,warp reinforcing threads 3 and 4 interlacewith the thread a of eve weft strand 1, thereb to estab ish a connection between the y weave and the reinforcing or stiffening mesh or gauze on the rearsurface of the body. The interlacing of adjacent warp stiffening threads 4 with the body weft strands 1 is preferably staggered, as indicated particularly in Figure 2, so that two adjacent stifi'ening warp strands 4 will not interlacewith the same body weft strands 1 but will interlace with every second or some intermediate body weft strand, depending upon the frequency of interlacing between the stiffening warp strands and body weft strands. By this means, the attachment ints between the body fabric and the reinorcing or stiffening mesh or weave is distributed more uniformly throughout the surface of the fabric. I

In the drawings, the fabric has been much enlarged so as more clearly to illustrate the invention and thus the 'spa'ces'between the weft strands and body warp strands have been likewise enlarged. Thus, in Figure 1, the stiffening weft and warp strands 3 and 4 are generally visible through the open spaces between the body weft and warp strands 1 and 2. In the actual fabric, however, the space between the body weft strands andbody warp strands is practically negligible so that the stiffening strands and 4 may fourth body be entirely invisible from the face surface of era ly madeof the same substance as the body stra ds and ofa cross-sectional shape generally so different from that ofethe body strands as to give the same a greater resistance'to bending for a given area of cross-sec- 'tion, interlaced with said body strands at suitable intervals, where-by a'desired resiliency may be imparted to the body of the fabric b Said stiffening strands by reason .of said di erence in cross-sectional shape andwhereby said relatively flat and bulky body strands will tend to cover and conceal said stifl'ening strands by reason of said difference in the aggregate or individual cross-sectional area between said body and stiffening strands. In the particular embodiment of my invention, the body strands 1 and 2 are composed of a plurality of flat, ribbon-like threads or filaments of artificial cellulose, such as visca; while the stiffening-strands 3 and 4 are single filaments of artificial cellulose of generally round cross-sectional shape.

By my novel construction, therefore, I am able to produce a fabric of any suitable Weave or,-texture and to .so reinforce or stiffen the fabric on the reverse side thereof as not to be at all visible on the face thereof and so as also wise, the resiliency in. these two directions may be varied by the amount or frequency of the stiffening strands running weft-wise and wags-wise, respectively. Thus, too, if y desir the stiffening strands may be extended only in one direction, either weft-wise or warp-wise. Thus, too, the body strands may be caused to cover and conceal thestifi'ening strands on either side of the fabric or on both sides thereof and to an extent desired.

Mynovel fabric fin s numerous applications, particularly in fabric designed for use in hats and the like. Thus, my invention is particularly applicable to the making of visca or artificial cellulose fabrics for ladies hats and the like, which the rear stiffening mesh or gauze attached to the rear face of the fabric will so stiffen the fabric as toafi'ord v the same support s'ufiicient to maintain the shape of the hat without any wire orany other bracing or sizin or the like.

The stiffening mes of my novel fabric may be formed of natural hair threads or artificial hair threads of artificial cellulose or the like, such as artificial horsehair, or in fact any suitable stiff thread.

I am aware that the invention may be embodied in other specific forms without departin from the spirit or essential attributes thereoi and I therefore desire the present embodiment to be considered in all respects as illustrative and'not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

Having. thus described my invention what I claim as new and desire to secure by Letters Patent, is
